Android不依赖okhttp处理SSE流式接口(如AI逐句回复)

参考别的前辈的代码，忘记在哪里看的了

InputStream is = null;
try {
    //1.设置URL
    URL url = new URL("http://.../chat");
    //2.打开URL连接
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    //3.设置请求方式
    conn.setRequestMethod("POST");
    //4.设置Content-Type
    conn.setRequestProperty("Content-Type", "application/json;charset=utf-8");
    //5.设置Accept
    conn.setRequestProperty("Accept", "text/event-stream");
    //6.设置DoOutput
    conn.setDoOutput(true);
    //7.设置DoInput
    conn.setDoInput(true);
    //8.获取输出流
    OutputStream os = conn.getOutputStream();
    //9.写入参数（json格式）
    os.write(new Gson().toJson(aiAskBean).getBytes("utf-8"));
    os.flush();
    os.close();
    //10.获取输入流
    is = conn.getInputStream();
    byte[] bytes = new byte[1024];
    int len = 0;
    while ((len = is.read(bytes)) != -1) {
        String line = new String(bytes, 0, len, "utf-8");
        //line就是每行的数据了，也就是“逐句”
    }
} catch (IOException e) {
    e.printStackTrace();
    
} finally {
    if (!Objects.isNull(is)) {
        try {
            //12.关闭输入流
            is.close();
            
        } catch (IOException e) {
            e.printStackTrace();
           
        }
    }

}
